IMPROVEMENT IN RUNNING-GEARS FOR WAGONS.

Specification forming part of Letters Patent No. 2 [9,457, dated September 9, 1879; application tiled July 8, 1879.

To all whom it may concern:

Be it known that I, WILLIAM T. GIBsoN, of Birdsdale, Bell county, State of Texas, have invented certain new and useful Improvements in Attachments for Coupling-Poles of Wagons; and I hereby declare the same to be fully, clearly, and exactly described as follows, reference being had to the accompanying drawings, in which- Figure l is a perspective view, and Fig. 2 a vertical longitudinal sectional view, of the device as applied to a courding-pole.

My invention relates to that class of wagons in which the tongue is supported by a crossbar connecting the' bounds behind the front axle and passing beneath the coupling-pole. The part of the pole against which the crossbar rests, as well as the bar itself, are sub-' jected to constant wear, as the cross-bar is continually sawing back and forth through a greater or less distance, according to the condition ot'the road, while the wagon is in motion.

It has been customary to face the cross-bar and the under side of the couplingpole at the point of contact with iron and keep this quasi tifthwheel well lubricated; but this expedient does not obviate or materially lessen wear. as

'the lubricant becomes full of sand and grit,

for the insertion of the attaching-screws d (7. Each part of the box B is provided with a hole for the journals 0 of the roller (1.

To insert the box a mortise is made on the under side of the coupling-pole, at the proper place, deep enough to be exactly filled by the box when its end flanges are in contact with the face of the pole. The roller being then inserted in the box, the halves b b are brought together, and the box is laid in the mortise and attached by screws d d. The roller exactlyfllls the box, so as to prevent the entrance of sand or grit.

I have not thought it necessary to illustrate in the accompanying drawings the'hounds or cross-bars, as their relation to the device which forms the subject of my invention is obvious.

When the journals of the roller finally wear out, a new one may be readily inserted upon removing the box. For this reason, as Well as to admit of the device being formed wholly by casting, I construct the box in two pieces.

The device maybe constructed at trifling cost, is readily attached to the pole, and 0011b pletely obviates what has heretofore been a fruitful source of annoyance.

What I claim as new, and desire to secure by Letters Patent, is-

The device herein described, consisting of the box B, adapted for insertion in a mortise in the couplingpole and made in two parts, each having a perforated flange, and the roller 0, journaled in the box, substantially as described.
